While  it won't be as much fun as eating candy bars, researchers have launched a big study to see if pills containing the nutrients in dark chocolate can help prevent heart attacks and strokes.  These chocolate pills will end up having all the good stuff, called coca flavanols, that have been known to improve blood pressure, cholesterol, the body's use of insulin, and artery health.  Unfortunatley for those taking part in the study, the chocolate pills have no sugar and no fat--so they're not tasty.  At all.  - Becky
